Does anyone sell a hose kit that contains all of the hoses in and around the carburetor? They’re all a bit cracked and I was hoping someone made an easy all in one package. If not, what do you recommend? I realize I can go to any decent auto parts store and get hose by the foot, though some of these hoses have special bends in them.

Thanks!

 

There's no kit like that. You'll just have to replace the vacuum hoses individually.

 

Yeah, here's your "kit".

 

I have a similar setup for the different gauges of wire, 14, 16, 18, 20. in various colors. About 100 ft. each. Very convenient to have.

 

What you really need, if you don't already have it, is this diagram from the '78 Chassis Service Manual. Make sure that all the hoses are present and accounted for and are properly routed.

You likely want the image in the upper left as that's the "normal" situation for the 350 in an 88. Upper right is for high altitude situations, and lower left is for cars originally sold in California.

When I needed vacuum hoses, I went to Amazon and bought two package each of four different-sized vacuum hoses. Rather than trying measure specifically what I needed in each size, I just did this, and that way I pretty much always had on hand what I needed as I gradually replaced everything in my '78 Toronado.






Now, if you want to know what those various initials (CTVS, TACS, TCV, EGR, etc.) stand for, look no further than three pages back. Can't tell the players without a program!

Note that things don't exactly match up. CTVS and EGR are shown, but TACS and TCV are not. But I think they're there under slightly different initials. TACS is there under "TAC," I believe. so it's Thermostatic Air Cleaner Switch?

TCV is not there, but DTCV is. Distributor Thermal Control Valve. I assume.

Leave it to GM to make up a detailed table like this and then not actually use the initials in their diagrams as they are shown in the table.
